Pizzeria under control
A solo control-chart trainer set in a pizzeria - the player watches three stations and reacts exactly when the process drifts out of control.
What is the Pizzeria under control game?
Pizzeria under control is a solo training game that teaches how to read control charts (Statistical Process Control). The player scans a QR code and runs a pizza line across three stations: slicing tomatoes (slice thickness), placing slices (slice count) and baking (oven temperature). Each station has its own Critical-to-Quality (CtQ) measurement and a control chart updated live.
With every pizza the machines wear down: the knife dulls, the machine drifts and the oven cools - the mean moves away from target, spread grows, and points start to escape the control limits. The player's job is to service the right machine exactly when a chart signals an out-of-control process - before pizzas fall outside specification - and to leave a stable process alone (over-adjusting costs money). At the end the game reports total cost, the number of defective pizzas and how accurate the services were.
Features
Key capabilities
Live control charts
Every CtQ shows its centre line, ±3σ control limits and warning zones, updated with each pizza produced.
Out-of-control signals
The game detects Western Electric rules - point beyond a limit, a trend, a run on one side and points in the warning zone - so players learn to spot them.
Service right on time
Sharpen the knife, calibrate the machine or maintain the oven - but only once a chart signals. Reacting at the right moment keeps quality up at low cost.
The tampering trap
Adjusting a stable process only adds variation and cost - the game scores services made with no active signal as premature.
Solo, by QR, no login
A single-player full-screen game - the participant scans the code or opens the link and plays on their own device, no account needed.
Player ranking
After a run the player saves their score under their name and joins the ranking - later groups have someone to beat.
Step by step
How it works
Share the game
Open the game page in the app and hand out the QR code or link - the game opens without logging in.
Watch production
Each pizza passes through three stations, and the control charts plot each new CtQ measurement.
React to the signal
When a chart signals an out-of-control process, service the right machine - and leave a process that's within limits untouched.
Review the summary
After the full run the game shows total cost, the number of defective pizzas and how accurate your service decisions were.
Use cases
What it’s good for
- Introduce control charts and ±3σ limits in an SPC, Six Sigma or lean training.
- Show the difference between natural variation and a true out-of-control signal.
- Demonstrate the cost of over-adjustment (tampering) with a live, tangible example.
- Use it as a warm-up or exercise in a quality- or production-management course.
- Explain control charts without a lecture full of formulas
- A hands-on exercise for an SPC or Six Sigma course
- Show that reacting to every wobble makes the process worse
